This bulletin has been amended. On pages 15 and 16, “For vehicles built after the applied VIN and date” was changed to “For vehicles built before the applied VIN and date”.
Please discard previous versions of this bulletin.

PPLIED VEHICLE: 2013 Altima Sedan (L33) PPLIED VINs and DATES: See the Repair Flow Chart on page 2.
YOU CONFIRM: he customer is experiencing a noise coming from the passenger side engine compartment nd he source of the noise is confirmed to be the Hydraulic Electric Power Steering (H-EPS) nd he noise is louder than the normal operational noise of the H-EPS.
NOTES:
• The 2013 Nissan Altima sedan is equipped with Hydraulic Electric Power Steering (H-EPS). This system uses an electric motor to drive a pump rather than relying on a conventional belt-driven pump. You may hear some normal operational noise from the front of the vehicle generated by the H-EPS when the steering wheel is operated.
• Comparing the incident vehicle to a “known good vehicle” will help determine if the H-EPS noise is louder than normal.
CTION: efer to the Repair Flow Chart on page 2.
PORTANT: The purpose of ACTION (above) is to give you a quick idea of the work you ill be performing. You MUST closely follow the entire SERVICE PROCEDURE as it ontains information that is essential to successfully completing this repair. issan Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are roperly trained individuals who have the equipment, tools, safety instruction, and know-how to do a job roperly and safely. NOTE: If you believe that a described condition may apply to a particular vehicle, DO OT assume that it does. See your Nissan dealer to determine if this applies to your vehicle.

NOTES: • A previous version of this bulletin did not include 6 cyl models.
• A previous version of this bulletin did not include replacement of the H-EPS bracket.
• Steps 1 through 17 (Inspect and Repair H-EPS) in this version are similar to the previous versions.
• If a previous version of this bulletin (op code QX22AA) was already applied to the vehicle you are working on, Inspect and Repair H-EPS does not need to be done again.

SERVICE PROCEDURE
Inspect and Repair H-EPS
Figure 1
Hatching area
1. Check the Hydraulic Electric PowerSteering (H-EPS) fluid level.
• Check fluid level with the
ignition OFF and fluid temperature between 0 – 30°C (32 – 86°F).
• Power steering fluid level
should be within the hatching area of the indicator on the power steering reservoir tank cap.
• If fluid is needed, use only
genuine NISSAN E-PSF or equivalent.
2. Make sure the right front hood ledge seal is installed correctly.
• Install seal correctly, or
• If damaged, replace seal, or
• If missing, install a seal.

3. Make sure there is no binding on the H-EPS pump mounting isolator as follows:
a. Loosen the 4 H-EPS pump
mounting bolts. b. Move the H-EPS pump a small
amount from side to side. c. Tighten the mounting bolts.
Torque to:
13.5 N•m (1.4 kg-m, 10 ft-lb)

5. Make sure the H-EPS high pressure line and the A/C low pressure line are not touching
(see Figure 5).
• Check the two locations circled in Figure 5.
• If the lines are touching, reposition the lines so they are not touching. 6. Make sure the H-EPS high pressure line is not touching the coolant reservoir
(see Figure 5).
If touching:
• Make sure the coolant reservoir is mounted correctly; its locator boss must be seated in the mounting hole.
• If needed, reposition the H-EPS line so it is not touching the reservoir.

13. Make sure the baffle is positioned properly inside the RH (passenger side) front fender.
• The baffle should be flush against
the fender.
• When the fender protector is installed there should be no gap between the fender protector and the baffle.
• If needed, reposition the baffle or
install a new one.
